CVE-2026-64477

CVE-2026-64477 affects Linux kernel (x86, fs/resctrl) where offlining a CPU with SNC enabled can trigger an out-of-bounds access. The root cause is that when a monitoring domain’s cpu_mask becomes empty, the NUMA node lookup uses nr_cpu_ids, leading to out-of-bounds during RMID reading. The mitig...

CVE-2026-64413

CVE-2026-64413 relates to the Linux kernel netfilter/ebtables path, specifically the zero chainstack array issue. The advisory describes that if cpu_possible_mask is sparse (e.g., CPU 0 and CPU 2 possible, CPU 1 not), the allocation loop can skip an entry and, if vmalloc_node() fails later, the c...
